Chondroitin sulfate

SKU: orb1304776

Description

Chondroitin sulfate is sourced from shark cartilage and should be stored in a cool, dry, sealed container. This glycosaminoglycan is widely used in research on osteoarthritis, cartilage repair, and extracellular matrix studies, with applications in both in vitro cell culture and in vivo animal models.

Bioactivity

• In Vivo:
  The high content of chondroitin sulfate in aggrecan significantly enhances cartilage's resistance and elasticity, enabling it to withstand tensile stresses under various loading conditions. Research suggests that chondroitin sulfate mitigates structural changes in joint tissues, supporting its use in treating osteoarthritis patients. Administered orally at 800 to 1200 mg/day, chondroitin sulfate is rapidly absorbed by the gastrointestinal tract, entering the bloodstream as 10% unchanged and 90% depolymerized low-molecular-weight derivatives.
• In Vitro:
  Chondroitin sulfate, a sulfated glycosaminoglycan comprising linear polysaccharides with repeating disaccharide units of uronic acid and N-acetylhexosamine, plays a critical role in the extracellular matrix of various connective tissues, including bone, cartilage, skin, ligaments, and tendons. It has been observed that various pathogens such as parasites, bacteria, and viruses exploit chondroitin sulfate on the cell surface for host cell attachment and infection. Beyond its natural occurrence, chondroitin sulfate exhibits multiple beneficial properties, including anti-inflammatory effects, promotion of type II collagen and proteoglycan production, reduction in bone resorption, and support for a positive anabolic/catabolic balance in chondrocytes. In vitro studies have employed a broad spectrum of chondroitin sulfate concentrations, typically not exceeding 200 mg/mL, demonstrating its capability to diminish chondrocyte vulnerability to apoptosis triggered by single nucleotide polymorphism at 200 mg/mL concentration. Moreover, it significantly lowers the levels of inflammation mediators, the apoptotic process, and inflammatory cytokine, iNOS, and MMPs production.
• Cell Research:
  Chondrocytes are cultured into six-well culture plates. 12 hours after plating, the culture medium is replaced with 2.0 mL of fresh medium containing LPS at a concentration of 50 mg/mL. 4 hours later, HA, Chondroitin sulfate, HS, keratan sulphate and DS are added separately to each of the wells at concentrations of 0.5 and 1.0 mg/mL. The number of viable chondrocytes is then quantified by trypan blue dye exclusion test from several randomly chosen areas of each well.
